Securing window clips

Good evening. I am trying to identify these two clips. These clips have a small notch on the bottom that, when the window is closed, hold the window secure in place. The second pic is the same but it is at the bottom of the window attached to the bar that runs across the bottom edge. I have several that are cracked or broken, which leaves the windows very easy to pull open. Is there any way to replace these clips? If so where do I get these from, and for the bottom one how would I replace that?

Thankyou so much for the direction on parts. A big question is, how do I replace the bottom one? (Picture with the arrow). It appears that the clips is attached to the metal rod, I've tried removing them and it wouldn't come out.

This is what I need. Finally got the bottom bar out.
